Seafood Sweet Potato Chowder
I know I’ve been sharing a lot of Instant Pot recipes lately, so for my readers who don’t have one, don’t worry – here’s a one pot meal that you don’t need an Instant Pot to make. 🙂
Corn chowder is a classic summer staple, but it’s also super cozy and can easily be made during the rest of the year! This is a lightened-up version that swaps out heavy cream for whole milk, which keeps it perfectly creamy.
Plus, it’s packed with lean protein and veggies like sweet potato, bell peppers, and sweet corn. So it’s highly nutritious but doesn’t skimp on flavor!

Recipe Ingredients
To make this seafood chowder recipe, you’ll need:
- ghee (i. e. clarified butter. Regular butter also works)
- onion
- bell peppers (any color, red is the sweetest!)
- sweet potatoes (You can also use gold potatoes, or any type of potato you like!)
- garlic
- dried thyme
- cayenne pepper
- corn (frozen or canned both work)
- whole milk (This adds a good balance of creaminess that isn’t not too heavy!)
- bay scallops (or crab, lobster, shrimp, etc.)
- tilapia filets (or other white fish, like cod. Salmon also works!)
- salt and pepper (to taste)
Pro tip: this soup is delicious paired with crusty bread or oyster crackers! Feel free to also toss in more veggies like diced carrots or celery for added crunch.
How to Make Healthy Seafood Chowder
Start by melting the ghee (clarified butter) in a large pot on the stovetop over medium heat.
Then, add the onion, peppers, garlic (hot tip: save time with garlic stir-in paste or pre-minced garlic), thyme, and cayenne. Cook until the vegetables are softened, about 5 minutes.
Toss in your diced sweet potatoes and corn and cook for another minute or so.

Next up: add the milk, then bring the mixture to a boil.
Reduce heat to low, cover, and simmer for about 15 minutes, or until the sweet potatoes are tender.
Once the sweet potatoes are soft, you’ll want to puree a bit of the mixture to add some body/mouthfeel to the soup. This adds creaminess without the need for heavy cream!
If you have an immersion blender, simply blend briefly/partially.
If you’re working with a regular blender, remove about 1/3 of the soup, blend it, and then pour it back in.

Now it’s time for the stars of the show: the bay scallops and the tilapia!
Simply toss them in the soup, then cook on low heat another 5 to 7 minutes, or until the scallops are opaque and the tilapia is flaky.

Now all there is left to do is ladle into bowls and enjoy!
I recommend savoring this healthy seafood chowder with a side of toast for dipping, but you do you.

Feel free to toss some scallions on there for a little color, too.
Either way – I hope you enjoy this cozy chowder!
